Hi,

1/ I used shortcode for your blockquote like this image and it's still working fine. You can take a look on this post.

2/ You can add more this code to Customize > Custom CSS to change colors for your blockquote:

\
.post-entry blockquote, .post-entry blockquote p, .wpb_text_column blockquote, .wpb_text_column blockquote p{ color: #0084cc; }

3/ You can change the font for it by do following steps:

a) Install & activate plugin Use Any Font

b) This plugin allow you can use more one custom font from your upload - if you want to use more font, you need to pay. When you get API key, scroll down this to left to get free API key, like this image

After installed this plugin, go to admin page > Use Any Font > get an API key free for one font upload and verify it and upload your font from add font like on this image

Add more this code to Customize > Custom CSS to change the font:

\
.post-entry blockquote, .post-entry blockquote p, .wpb_text_column blockquote, .wpb_text_column blockquote p{ font-family: 'Your Font Name'; }

Note Important: Change Your Font Name on above code to the font name you fill like on this image.
