I've installed hackintosh, but have some troubles

[ChA0S_f4me]

My hardware:
AMD Ryzen 5 3500H laptop
NVIDIA GeForce 1650 laptop

I've installed Big Sur, but in graphic it displays "Display 7 MB":

And I've laggy desktop

2nd question: can I use nvidia graphic card?
3rd question: When I booting to PC, it goes to standart startup, not clover bootloader. I need use clover bootloader from USB for boot to hackintosh

Last question: can I use Wi-Fi? Card: Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

No, you can't use that Nvidia graphics card. It has never been supported in macOS. So you can't fix the laggy graphics or increase the amount of RAM available to the GPU.

Realtek WiFi cards are not supported in macOS. Broadcom are natively supported and Intel with use of IntelWireless kexts.

You have done well to install macOS on your system. But unfortunately, you won't be able to improve the graphics performance or get the Realtek WiFi working.
