I want to do maths, Physcology and economics/geography (or both depending on school)

Have you looked into the entry requirements for any of the colleges?

Also, which subjects do you intend to study? It's very difficult to say without knowing this.

Let's look at LAE for example. The following are their page for their entry requirements:
https://www.lae.ac.uk/399/entry-requirements#

General entry requirements:

You have been predicted nine 9-7 GCSE grades.
You have been predicted at least a grade 6 in both Maths and English Language

Requirements for Maths are: If taken with a Humanity or Social Science A level subject, GCSE Maths 7+ (which you are predicted to meet)
Requirements for Psychology are: GCSE Maths and/or English Language plus Science GCSE (preferably Biology) (both 7+, which you are predicted to meet)
Requirements for Economics are: GCSE Mathematics plus GCSE English Literature or Language (all at 7+, which you are predicted to meet)
Requirements for Geography are: GCSE Geography plus GCSE English Language and/or Maths (all at 7+, which you are predicted to meet)

So from the look of things, you should be able to meet the requirements of the course. The thing you would need to bear in mind is the level of competition for getting a place at the college. If the competition is fierce, they might pick the applicants with the higher grades.
I cannot see the application form without signing up, so I can't comment on the questions that they will ask you. However, they do offer only a guidance meeting after submitting your application and not necessarily an interview, meaning there is a chance they would only consider your grades and less about the applicant's background.

I am not going through the other colleges, so you would need to do this yourself.

Good luck on getting the GCSE results though. They're going to be important if you want to apply to these colleges.

Comment on your subjects: Why are you picking economics or psychology? I can understand why you might want to pick maths with economics or geography, but the mix doesn't quite go that well with psychology.
If you wanted to do a degree in economics, you would only need maths. If you want to do a degree with a lot of physical geography, then you would need geography.
If you want to do a degree in geophysics, geology, or earth sciences, you would need maths and geography (ideally physics, but you might be able to get into some universities with geography).
It's on the rare occasion that you would need psychology for any psychology degree. Likewise, no university would be asking for economics for any economics degree.
If you wanted to do a degree that asks for any subjects (e.g. law, business, anthropology), then you could have easily picked any academic subjects of your choice. Maths, being one of the subjects you're predicted with the lowest grades in and not being known for an easy subject, wouldn't have been a subject I would have thought you wanted to do if this was the case.

Thank you, yes I'm applying for psychology because that is a subject I enjoy especially the Forensic part.
Yes I'm quite shocked I got predicted a 7 as usually I get 8s in mathbut I didn't do aswell this time but I know and will definitely get a 8/9 in my actual gcses, and I want to do a degree appreciate in finance because it has a variety of degree apprenticeships I can apply for and my alevel subject choices aren't restricted. Moreover, the salary is quite high compared to others at entry level and I'm looking to move out before 25 due family issues. Also, I actually enjoy maths even though its difficult at time and I know it's something sustainable for the long run.
I have looked into entry requirements from these places however I'm at the lower end of spectrum and worried about competition.
However, I have decided not to worry about it as I can contact them on results day to see if I can get an offer if I don't now. Even if I don't make it in despite my grades improving to all 8s and 9s then it just means I will have to be more independent seeking supercurriculars and studying even harder. Which I can use in my personal statement to show my determination and drive to my focus on this career despite being in a low progression go russel uni schools as around my area there aren't many outstanding schools, so I'm reaching quite far out.
