Can I activate this card's <Main Timing> effect to place 5 cards with [Hybrid] in their traits under this Tamer from my trash, and then choose not to digivolve into [EmperorGreymon]?
Yes. The card text reads, “you may,” so you can choose to only place 5 cards with [Hybrid] in their traits under this Tamer without digivolving.

This card has a digivolution card effect, how can I activate it?
It can be activated after the tamer has evolved into a Digimon card that can digivolved from the tamer and this card is the digivolution card from the tamer to the digivolved Digimon.
Can I use this card's [Main] effect to put 5 cards with "Hybrid Body" in their traits from my trash under this tamer and dare not digivolve to "EmperorGreymon"?
Yes, it is "can digivolve", so it is possible to put 5 cards with "Hybrid Body" in the trait from the trash under this tamer without digivolving to "EmperorGreymon".
When there are only 4 cards with "Hybrid Body" in the trait in my trash, can I use this card's [Main] effect to put only 4 cards from my trash under this tamer, even though it cannot digivolution?
No, I cannot.
