How can the two microphones be used at the same time?

as another reviewer has mentioned, each microphone has to be set up on a different channel (see the instructions). Basically plug the receiver into the amp or mixer channel you wish to use then set the first microphone to a channel ( see instructions) the last microphone is then set to a different channel and linked the same way. Now you're set! Be aware that they will not have individually controlled volume since they'll be sharing the same amp/mixer input. IF you want individual volume control, you'll need to plug each receiver to a different amp/mixer channel! The mics are really good and a single channel should work fine! I hope this helps!

Can I buy extra receiver only

Yes. https://www.amazon.com/dp/B0B9SMYS4J

I feel that there is delay when i connect this device to an amazon echo speaker. should i change the speaker?

I have the same problem with delay - need answer soon !!

Does it support laptops? Or a bar speaker?

This should be fine, as the machine has three output modes, RCA 3.5mm and 6.35mm, and you can choose different connection modes according to your device
