Keep you from phil = manter voce longe phil
His laziness keep him from work= a preguisa do cabra o impede de trabalhar
Tudo certo?

Answer 1

It keeps you from sleeping (when a verb comes after a preposition, you have to add -ing).

Keep you away from Phil (keep away is what you're looking for here. Also, you might need to add a subject, just in case your teacher is too fond of pristine grammar).

His laziness keeps him from working. (his laziness = it, so you have to add -s to the verb).
