LS47 Cipher is a slight improvement of the ElsieFour cipher as described by Alan Kaminsky. It use 7x7 characters instead of original (barely fitting) 6x6, to be able to encrypt some structured information. It also describe a simple key-expansion algorithm, because remembering passwords is popular.

ChaCha Cipher is a stream cipher designed by Daniel J. Bernstein. It is a variant of the Salsa stream cipher. Several parameterizations exist; 'ChaCha' may refer to the original construction, or to the variant as described in RFC-8439.

Fernet Cipher is a symmetric encryption method which makes sure that the message encrypted cannot be manipulated/read without the key. It uses URL safe encoding for the keys. Fernet uses 128-bit AES in CBC mode and PKCS7 padding, with HMAC using SHA256 for authentication.
