Could someone answer me this?

I’ve noticed that bb8 counters when he has foresight, even though he wasn’t actually hit but other characters that have counter will not do so when they have foresight is there a reason for this?

Some attacks cannot be evaded, for example: Vader's saber throw and R2-D2's AoE Burn. These attacks go through Foresight so that can trigger BB-8's counter-attack, but he'll still have the Foresight. Hope this answers your question.

If this doesn't answer your question could you mention what specific characters BB-8 is countering when other characters are not?

This is for palp aoe and DN using his ability drain force both of these trigger a counter attack yet they shouldn’t since they can be evaded.

I’d rather this be delt with I run a nightmare squad and this can really screw up a run with he continues to call asisst when he shouldn’t be
