If spirit monster's effect is negated for 1 turn, does it return to hand by end phase?
No, It Does Not Return To Hand

The effect written on Spirit monsters is an activated effect, which activates during the End Phase. When a monster's effect is negated "until the end of this turn," this applies throughout the End Phase; i.e, the effect(s) will be negated until the beginning of the next player's turn.

Case 1:

Forbidden Chalice negates the effects of Dark Dust Spirit until the end of the turn. During the End Phase, the effect of Dark Dust Spirit will activate, but be negated by Chalice - Dark Dusk Spirit remains on the field.

Case 2:

The effect of Dark Dust Spirit activates during the End Phase. Because Dark Dust Spirit is a face-up monster on the field, that effect will be negated by Skill Drain - Dark Dust Spirit remains on the field.

It Will Remain On The Field Each Turn

The effect's activation timing is "During the End Phase of the turn this card is Normal Summoned or flipped face-up:". After that initial turn of its summon has passed, the effect will not activate again on any subsequent turn - unless, of course, it incidentally happens to be flipped face-down and back up again.
