Identifont and WhatFontIs to find free fonts to similar to proprietary ones

OK, in trying to work with a presentation that is using a ton of proprietary fonts. Here are some tools:

Figure out what font it is with TypeSquirrel or WhatFontIs or FontSpring from just an image. Or use the Chrome WhatFontIs extension to determine what font you see on a website.
Figure out what a free font equivalent. This is actually hard that it looks if you want to use on a website, Keynote or PowerPoint. You need to download the fonts with WhatfontIs and it will give you the free alternatives, so for instance Alternatype works for the basic fonts and Identitype works, but mixes in free and paid fonts.
Figure out what Google Font is most equivalent. First, just try to type the name of the font into https://google.com/fonts. There don’t appear to be any tools for this, but there are curated font lists from folks like Typewolf that give you some good alternatives or hand curated lists like Rika or fonts that look good together from Zach
As always if you have the means, please support independent typographers if you can. As you would any artist.

Then you can download the TTF and use iFont on iOS to install them and use them with Keynote.

So here are some equivalents starting with Google fonts, so let’s apply this to the font set problem. A presentations has:

Titillium
Ubuntu
GT Haptik
NFC Giza Seven Three
Franchise

The answer (TL;dr) can be put on a website with

<link href="https://fonts.googleapis.com/css?family=Alfa+Slab+One|Poppins|Teko|Titillium+Web|Ubuntu&display=swap" rel="stylesheet">

And you call it with a CSS sheet:

font-family: 'Titillium Web', sans-serif;
font-family: 'Ubuntu', sans-serif;
font-family: 'Alfa Slab One', cursive;
font-family: 'Poppins', sans-serif;
font-family: 'Teko', sans-serif;

What are the open source and then the Google Font equivalents

Titillium and Ubuntu are on Google Fonts without translation

WhatFontis – GT Haptik is similar to Madelyn Sans which is an open one. As an aside, Identifonts let’s you create Fontsets or collections. The main problem is that it doesn’t tell you what the costs of the fonts are. Going through manually and typing for names in Google Fonts and Poppins seems to be the closest
