Sure thing, I'll list it below:
1. I start with Tricep extensions
https://m.youtube.com/watch?v=VYgVTinbx_A You might have to start on your knees if these are too difficult to begin with. Consistency is important. These are great for triceps which is what you want to get bigger arms (I do it to hide my elbow bones) 8 reps of these, 3 sets
2. & 3. Diamond push-ups 8 reps, 3 sets. Close push-ups 8 reps, 3 sets
4. Once the above have been done (all together, so extensions, diamonds and then close push-ups in that order) then I move onto my weights. I do 8 reps 3 sets of Skull crushers with an ez bar at 25kg. Capped at this since there are no more weights at home
5. Wide arm chin ups for a bit of back muscle development. Again, 8 reps, 3 sets
6. Reverse bicep curl using a barbell. Only 10kg. My forearms are tiny atm. 8, 3
7. Forearm curls (wrist curls into my arm towards my bicep). 10 reps, 5 sets on my left arm due to under development. Only 3 sets on my right arm
8. Hammer curls, currently working back up to 10kg since I've been ill. Same reps and sets as forearm curls
9. Maximum effort 25kg EZ bar bicep curl
This might be a bit much so I recommend just doing the first 5 or so exercises (or less) just to settle into it then work from there.
I'll pm you a calisthenic routine I used to do which helped a LOT literally within a month and a half. That might be better since you don't have to commit and get the motivation to go gym
