Can I use the same wallet?

Can I use the same Trezor T device to save coins on Suite and connect to other wallets like a metamask or syscoin wallet? Or is better to use different devices?

use the same device is better.
and if you use erc20 chain , use the address that suite shows as metamask eth wallet address is better

If my Metamask is BSC can I use the same Trezor or I should use another for this? Sorry if sounds silly I am a noob

use the same trezor
and your seed phrase ,write down at least two copies ,save them in different houses,not rooms , houses !
This year I have seen cases where at least 5 people wrote a seed phrase and then lost it, resulting in the loss of assets.
