The one single pointed lesion looks like wart. It's an infection. It needs to be treated. If not chances of spreading is there. Do not keep on touching the lesion with fingers, as it increases chance of spread.
The other two soft lesions look like skin tag(acrochordon). No need to worry about this, but can be removed..
But, need clear pictures for proper diagnosis and treatment
Next Steps
consult me online/any Dermatologist for proper treatment
