Hello,

You can add custom css code to change them, there are no such options.

Can you show me the link where you have the testimonials and what do you want to change?
I will give you some css code.

Best regards!

Hello,

What element are you using? You can show me a screenshot of it illustrating which padding do you want to change.

Best regards!

Hello,

Please add these lines at Css box

.single_testimonial .dl-horizontal dt {
  display: none;}
.single_testimonial dl dd {
  margin-left: 0px;
}
.single_testimonial dl dd p {
  text-align: center;
  padding: 21px;//here you cna change the testimonial content padding
}
.single_testimonial .param h6{
//here you can put extra css style for the testimonial title.
}
.wpcf7-form p input[type="submit"] {
  border-color: #fff !important;
  color: #fff !important;
}

Also you can remove the empty columns round the testimonial if you want it full width.

Best regards!
