ya i did n my teacher said its alrite to exceed 1sf than the lowest sf in question anyways it should kept to lowest i.e in a given set of values say 25000 2135 21.2112 the answer during calulation would be to 2sf or 3 rite

Its always safe to use 2/3 sf.

I've only ever seen marks deducted for just using 1sf.

if they ask you to put it to an appropriate number of significant figures, do the same as the question, but I go 2 or 3 which is fine with most mark schemes
