The transformer is buzzing a lot when i install the leds, what tipe of transformer should i use to replace it?

It depends a lot on the load (how many LEDs and the rated current). This is a good general purpose dimmer that works well with LEDs: https://www.amazon.com/Lutron-Incandescent-Single-Pole-Multi-Location-MACL-153M-WH/dp/B008X3CHM0

Do these bulbs make a buzzing sound?

Since this is a 12V bulb, it need a transformer to works with, so if you used a halogen type transformer , it may flicker or buzzing, but if with LED type transformer, it works perfectly, thank you

1 st one in string blinking others also blinking changed 1 st back to halogen all blinking stopped?

Dear customer, our led light bulb is compatible with LED transformer( AC120V to DC12V ) , if with halogen type transformer , this light bulb will possible blink , thanks .
