How could I create a buffer for each set of points (colour group) separately and in one procedure in QGIS 3?

The image below shows a subset of points for buffering.

In your Attribute Table, you need to create (unless you already have it) a field which will define the unique buffer distance for each of your points.

Then you will be able to accomplish the buffering process by applying

Vector > Geoprocessing Tool > Variable distance buffer

P.S. Be careful with units. The buffer size is always applied in the layer CRS units.

Alternatively, there is a way to accomplish this task with MMQGIS plugin.

I provide a short practical example based on Airports data from Natural Earth.

In Attribute Table of the Airports layer, I will use an already created attribute "wdid_score" which is an integer type and looks like distance in meters.
Example_of_the_attribute

Then (after CRS adjustment) I proceeded with Variable distance buffer. See image below.
Variable_distance_buffer

Thanks Taras - I see, but needed to buffer each group separately using the same radius - found a response from @Kazuhito suggesting just to buffer all together then dissolve on attribute basis (Dissolve tool GDAL)..this worked!

@Bruce T., can you please adjust your question in case if I misled the idea behind it. And by any means @Kazuhito deserves appreciation, however, it would be nicer if you @Bruce T. can embed his response into your question as a reference. Thanks
